I'm sure you noticed, but around 4:12 is actual footage of the infamous Sphinx mini boss from Rockman 4. BMF speculated on twitter that it may have been cut for difficulty concerns. It sure looked cool though.

I was kind of surprised to see Genesis Populous previewed in that original video. I thought that was a licensed game said to be incompatible with TMSS consoles. (was that even so with the Japanese version, which according to GameFAQs was published by Sega than EA)
Supposedly "consoles that didn't include Sonic the Hedgehog" was how they described the compatibility.
